MEANS FOR OPERATING DOORS.

Specification of Letters Patent. Patented play 39 1916 Application filed October 26, 1914. Serial N 0. 868,766.

To all whom it may concern Be it known that I, GEORGE B. KorILER, a'citizen of the United States, residing at Philadelphia, Pennsylvania, have invented certain Improvements in Means for Operating- Doors, of which the following is a specification.

One object of my invention is to provide a simple and effective means for opening and closing doors, particularly those of passenger cars, which are usually located at the side of the car at either end, or at the middle, and which are generally arranged in pairs.

Another object of the invention is to so construct and arrange the mechanism that either one of the doors can be opened or closed independently of the other, or both doors can be opened in unison.

A further object of the invention is to construct the mechanism so that it can be located at one side of the platform, the operating elements being arranged on a horizontal pivot.

In the accompanying drawings: Figure 1 is a sectional plan view illustrating one end of a passenger car and platform with the two sets of doors in the closed position and the steps raised; Fig. 2 is a sectional elevation looking from the interior of the platform toward the doors and showing the doors and steps in the same position as illustrated in Fig. 1; Fig. 3 is a vertical sectional view on the line aa, Fig. 1; Fig. 4 is an enlarged view of a part of the mechanism similar to that illustrated in .Fig. 3; Fig. 5 is a sectional view on the line b?), Fig. 4; Fig. 6 is a detached perspective view,

9 which is provided with a pin 9", which enters a slot in the handle 10 so that the spindle will turn with the handle. Located between the bracket 8 and the plate 7 and secured to the spindle 9 is an arm 11, which is connected by a rod 12 to an arm 13 of a three-armed lever 14 mounted on a stud projecting from a bracket 15 secured to the car frame structure under the platform. The arm 16 of the lever 14 is connected by secured to the inner section of the door '5 so that, when the operating lever is turned, the door will be opened andclosed. The arm 21 of the lever 14k is connected by a rod 22 to a bracket 23 on the step 24, which is pivoted at 25 to a bearing plate 26 which is, in turn, secured to the framework of the car so that when the doors are opened the step is lowered and when the doors are closed the step is raised.

The bracket 8, as illustrated in Fig. 5, has an extending hub 27 in which the shaft 9 is mounted and this hub also forms the bearing for a sleeve 28 on one end of which is the handled operating lever 29 and which has a slot to receive the pin 28 on the said a rod 17 to an arm 18 on the lower pivot' 19, which is firmly attached to a bracket 20 showing the elements for connecting the sleeve. On the other end of the sleeve is 40 operating means for one set of doors and an arm 30 connected by a rod 31 to an arm step; Fig. 7 is a perspective view showing 32 on a shaft 33 extending longitudinally the element connecting the other operating of the carunder the platform and back of means to the other set of doors and step; the steps and this shaft isadapted to bear- Fig. 8 is a perspective View of the counterings 15 as shown in Fig. 2. On the end 45 balance for the step, showing the step in of the shaft is a lever 34, which is con- 10o dotted lines and in the lowered position; nected by a rod 35 to an arm 36 on a pivot and Fig. 9 is a perspective view, showing 37 of the door (3. On the shaft 33 is an the elements of the compensating means dearm 38 connected by a rod 39 to the step tached. 24%, which is below the door 6, so that on 50 Referring to the drawings, 1 is the frame turning the operating lever 29 the door 6,

of the car. and its step, can be opened or closed.

2 is the platform. It will be noticed that the pivot 19 of the 3 is the outer bulkhead of a platform of door 5 is located some distance from the end the ordinary construction. of the door and also some distance from the 55 The doorway at one side is divided by a platform so as to allow the inner portion of the door, when it swings, to extend over the platform, While the pivot 37 of the door 6 is in line with the door and when the door is in the full open position it projects entirely beyond the platform. This particular construction may be modified without departing from the essential features of the invention.

In order to lock the two levers 10 and 29 together, when it is desired to open the doors 5 and 6 simultaneously, pivot a locking lever 40 at 41 on the operating lever 29 and one arm of this locking lever is in the path of a spring push pin 42 in the han vers at the side of the platform, as indi-- cated, so as to be within easy reachof the conductor, whose station is at the platform, these levers may be located at any predetermined point, according to the station of the conductor, or it can be located so that the motorman can operate the doors, as in some types of cars this duty is performed by the conductor and in other type it is performed by the motorman.

In order to counterbalance the steps 24, 1 preferably mount a spring 45 on a rod 46, which is pivoted at 47 to a bracket 48 which carries the step pivot pin 25. This pin passes through an opening in the bracket 48 and through openings in the casing 50, which is secured to the step and is made as illustrated in Figs. 8 and 9. forms a slot for the block 51,'in which the end of the rod 46 is mounted. Aset screw 52 extends through a threaded opening in the casing and bears against the block so as to regulate the tension of the spring 45. Thus, when the step 24 is lowered, the spring is compressed, according to the The casing i amount of space between the pivots 25 and 47 and the spring being under compression, when the step is, lowered, aids 1n elevating the step when. it, is raised.

above the platform; a lever mounted on the hub of the bearing under the platform, one arm of said lever being connected to one of the actuating mechanisms; a pivot for one of the doors to which the other arm of the lever is connected; an arm on each end of the shaft; a door pivot to which one of said arms is connected and the other arm being connected to the other operating mechanism.

2. The combination in means for operat ing doors, of a plate having a bearing thereon, said bearing having a tubular extension; a spindle mounted in the tubular bearing; an arm secured to they spindle at one end; an operating lever secured to the spindle at the other end; a sleeve loosely mounted on the tubular extension and having an arm at one end; and an operating lever at the other end.

3. The combination inmeans for operating doors, of a plate having a bearing thereon; said bearing having a tubular extension a spindle mounted in the tubular bear ing; an arm secured to the spindle at one end; an operating lever secured to the spindle at the other end; a sleeve loosely mounted on the tubular extension and having an arm at one end; an operating lever at the other end; and a latch on the last mentioned operating lever arranged to engage the other operating lever when it is desired to turnthe shaft and the sleeve in unison.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses. j
